Abstract
The utility model provides a three -way valve is inserted soon to integral type, belongs to the medical instrument field, the utility model is used for oxygen uptake and fog inhalation, it is more convenient, more laborsaving to make the humidifying device installation dismantle, and oxygen uptake and fog inhalation's conversion is more nimble, reduces nursing intensity, saves the nursing time. In order to reach above purpose, the technical scheme who takes is: design a three -way valve is inserted soon to integral type, including base, swing handle, three way connection, torsional spring, to being three way connection, swing handle, torsional spring, base in proper order down, base and swing handle pass through torsional spring swing joint, three way connection and base fixed connection on the follow. The torsional spring stretches out the angle that the straight angle is stretched out into at both ends, and the base is connected to one end, and the swing handle is connected to one end, and under the natural state, the torsional spring is lax state, and when applying external force on the swing handle, the torsional spring is the stress behind the swing handle of unscrewing, loosens the swing handle, and the torsional spring rebounds into natural state. Three way connection links to each other with the flowmeter tee bend, generally need not frequently take off. Consequently, during the use, only with a hand -screw division swing handle, hold humidifying device for one, can accomplish humidifying device's installation and take off the operation, convenient operation, swift, laborsaving.
Description
Technical field
This utility model belongs to medical instruments field, and particularly a kind of integral type inserts three-way valve soon.
Background technology
Clinical when carrying out breathing and oxygen inhalation therapy, oxygen inhalation therapy and nebulae inhalation usually can need to intert to be carried out, but oxygen inhalation therapy needs to carry out humidifying process, and nebulae inhalation then can not carry out humidifying process, and the two can not flexible conversion.In view of above reason, we have invented " a kind of Quick plug three-way valve special for oxygen inhalation " (notification number: 202263277U), comprise effusion meter interface, rotary spool, valve body, atomization interface, push-in humidification device interface, by the air flue that the on-off control of rotary spool is different, and then realize the conversion to oxygen uptake and atomization.After the said goods listing, clinical feedback will be docked with humidification device due to the push-in humidification device interface of above-mentioned three-way valve, and plug is more difficult, and therefore suggestion improves.In view of the inconvenience existed in Clinical practice, we have invented " a kind of rotation inserts three-way valve soon " (notification number: 203620036U), the plug-in type structure of former " a kind of Quick plug three-way valve special for oxygen inhalation " is improved to and rotates push-in structure.When carrying out nursing procedure, only need rotate swing handle gently, humidification device just can fall naturally, more laborsaving.But, above-mentioned " a kind of rotation inserts three-way valve soon " still has problems, such as, nursing staff needs one to hold swing handle when operating, one holds Connection Block could rotate the fast three-way valve of inserting of rotation, and has no time to attend to the humidification device unclamping whereabouts, there is not convenient part.
Summary of the invention
This utility model provides a kind of integral type to insert three-way valve soon, solves the not convenient problem of operation that prior art exists.
In order to reach above object, the technical scheme taked is: integral type inserts three-way valve soon, comprise base, swing handle, three way cock, torsion spring, it is three way cock, swing handle, torsion spring, base from top to bottom successively that described integral type inserts three-way valve soon, base and swing handle are flexibly connected by torsion spring, and three way cock is fixedly connected with base.
As concrete technical scheme, described base comprises column and the sealing gasket of inner hollow, and column and sealing gasket all have through hole, and column bottom sets firmly the platform placing sealing gasket, and column side is level and smooth or set firmly screw thread or draw-in groove.
As concrete technical scheme, described three way cock comprises effusion meter interface, rotary spool, valve body, atomization interface, push-in humidification device interface, sealing column, sealing column is positioned at the bottom of push-in humidification device interface, and there is through hole inside, and described through hole is connected with column;
The external diameter of described sealing column is less than or equal to the internal diameter of column, and when described three way cock is connected with base, sealing gasket is pressed on the platform in described column by described sealing column.
As concrete technical scheme, described three way cock screws in base by thread, draw-in groove sticks into, mode that is bonding or that weld closely is fixedly linked.
During use, three way cock is fixed in effusion meter threeway, push-in humidification device interface connects oxygen uptake humidification device, when carrying out oxygen uptake, a hand-screw rotates handle, the air inlet of humidification device is inserted push-in humidification device interface by the hand-tight humidification device of holding of another, and unclamp swing handle, humidification device just can insert closely in described interface and not get loose.When oxygen uptake is complete, a hand-screw opens swing handle, and one holds humidification device, easily can take off humidification device.When carrying out nebulae inhalation, the rotary spool on swivel tee joint is to " atomization " position, and will be atomized flexible pipe access atomization interface, can carry out nebulae inhalation, conversion is flexibly, easy to operate, and structure is simple, is worthy to be popularized.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, base, 2, swing handle, 3, three way cock, 4, torsion spring, 5, effusion meter interface, 6, rotary spool, 7, valve body, 8, atomization interface, 9, push-in humidification device interface, 10, sealing column, 11, column, 12, platform, 13, sealing gasket.
Detailed description of the invention
Below in conjunction with concrete embodiment, this utility model is further described.
Integral type inserts three-way valve soon, comprise base 1, swing handle 2, three way cock 3, torsion spring 4, it is three way cock 3, swing handle 2, torsion spring 4, base 1 from top to bottom successively that described integral type inserts three-way valve soon, and base 1 and swing handle 2 are flexibly connected by torsion spring 4, and three way cock 3 is fixedly connected with base 1.
Described base 1 comprises column 11 and the sealing gasket 13 of inner hollow, and column 11 and sealing gasket 13 all have through hole, sets firmly the platform 12 placing sealing gasket 13 bottom column 11, and column 11 side is level and smooth or set firmly screw thread or draw-in groove.
Described torsion spring 4 two ends are stretched out, and extension is divided into the angle being less than the straight angle, and torsion spring 4 is enclosed within column 11, and extension one end is connected with swing handle 2, and one end is connected with base 1.
The general state of torsion spring 4 is relaxed state, and when artificial rotation swing handle 2, torsion spring 4 also rotates thereupon, and become stress, unclamp swing handle 2, torsion spring 4 rebounds into relaxed state.
